WINDOW Filed March 14, 1930 2 Sheets-Sheet l Patented Aug. 11, 1931 UNITED STATES MICHAEL J. TRACY, OF ST. LOUIS COUNTY, MISSOURI WINDOW Application filed March 14, 1930. Serial No. 435,689.

This invention relates to windows, and has special reference to barred windows for use in institutions and elsewhere so that, while the Windows admit light and are capable of adjustment to permit the passage of air, it is impossible for persons to pass through the windows.

An object of the invention is to provide a window having panes for the passage of light and having openings for the passage of air and closures for said openings, in combination with means for moving the closures to open positions to permit the passage of air and to closed positions to exclude the air, and arranged so that, when the closures are in closed position, they will cooperate with the panes to prevent rain and snow, etc. from passing through the windows.

Another object of the invention is to provide a window embodying the construction and capable of the operation mentioned, in combination With means for barring and preventing the passage of persons through the windows even though the panes should become broken and the closures should be removed.

Other objects will appear from the following description, reference being made to the acompanying drawings, in which Fig. 1 is avertical longitudinal sectlonal View of my improved window.

Fig. 2 is an outside elevation of the window.

The window frame may be constructed in various ways and is preferably made of-metal. In the embodiment shown, there is at each side of the window opening a vertical angle bar rigidly secured to the wall of the building. These angle bars may be rigidly attached to the building wall by any desired fastening means, as by embeddin the lateral flanges 1 of the angle bars, while t e angle bar flanges 2 extend inwardly toward the inner side of the wall. A series of metallic bars 3 extend transversel of the window opening and have their ends rigidly attached to the angle bar flanges 2. These bars 3 are incapable of longitudinal movement and cannot be bent without the application of extraordinary force requiring powerful machinery or levers, such as are never available to the inmates of the institutions in which the windows are used and which are never readily available for use from the outside. The ends of these bars 3 may be extended through holes in the flanges 2 so that the ends of said bars 3 are close to the surfaces of the building wall 4 at the sides of the window opening. These bars may be specially constructed with longitudinal ribs or flanges 5 along their outer sides and with longitudinal flanges 6 along their inner sides. These bars 3 may beof duplicate construction andcut to the proper. length for use in the Windows as desired.

Each window frame also has at each vertical side'thereof a frame member composed preferably of substantially impenetrable sheet metal shaped to provide a wall 7 having along its inner edge a flange 8 attached to the building wall 4. The outer edge of the wall 7 extends substantially beyond the inner edge of the flange 2 and may be provided with notches or holes through which the bars 3 may be extended in order to obtain a more 8 rigid and secure construction.

The outer portion of each side frame member is composedof a metallic sheet 9 having its outer portion shaped to provide a flange 10 rigidly secured to the building wall 4 or to the angle bar member 1-2, or secured both to the building wall and to said angle bar member. The plates 9 extend inwardly be yond the outer edges of the plates 7 and are spaced laterally therefrom so that there is suflicient space 11 between the plates 7 and 9 (Fig. 4) for the mounting and for the operation of the connections for movin the closures for the ventilating openings to c osed and to open positions. The inner edges of the plates 9 are shaped to provide downwardly and inwardl inclined shoulders 12 which form seats or the movable closures when said closures are in closed positions; and to provide edges 13 inclining downwardly and outwardly from intersection with the shoulders 12. The lower ends of the edges 13 are approximately in the same plane as the next lower shoulders 12, respectively. Appropriate notches 14 for recelving the ends of the bars 3 are between the shoulders 12 and the lower ends of the inclined edges 13.

Corresponding to the series of bars 3 a series of inclined bars 15 is provided and rigidly attached to the window frame memhers 7 opposite the lower edges of the shoulders 12. These bars 15 may be made of hard metal or other appropriate material, and, if

desired, may be covered by covers 16. When thus arranged, the upper edges of the covers 16 are approximately in alinement'with the shoulders 12, being inclined downwardly and inwardl from said shoulders 12. A series of win ow sash holders is attached to the frame members 7 a ainst the inclined edges 13. As shown, eac of these window sash holders comprises a channel 17 having its lower end seated upon the flange 5 and having its upper end seated against the bar 15. Thus the channels 17 are arranged in pairs, one channel of each pair being secured to the plate 7 at one side 0 the window frame, and the other channel being secured to the plate 7 at the opposite side of the window frame. These channels are parallel, so that thetransparent or translucent panes 18 may be placed therein with their lower edges seated upon the flanges 5 and their upper edges seated against the upper edges of the bars 15. Putt or other sealmg material 19 fills the channe s 17 at the outer sides of the panels 18, thus providing impervious weatherproof jointse panels 18 in proper position and securing t in their supporting frames. It is now clear that these panels 18 are arranged on the louver principle, including downwardly and outwardly so as to discharge therefrom rain and other substances coming into contact with the outer surfaces thereof. This leaves a space between the upper edge of each pane 18 and the adjacent ar 3. These spaces are provided with closures which are movable to positions to open and to close said spaces. Each closure comprises an upper metallic plate 20, a lower metallic plate 21 having along its lower margin a downturned edge 22 and along its upper margin a downturned edge 23. Between these plates 20 and 21 a resilient metallic strip 24 is secured, so that the assembly comprising said three plates 20, 21 and 24 is a unitary member. The lower mar 'nal edge 25 is flexed downwardly so that w en the device is'in closed position, the edge 25 seats closely against the bar cover 16, while the flange 22 is against the upper edge of said cover 16 and the flan e 23 is against the lower edge of the bar ange 6. Each of these closures has rigid therewith at each end an upwardly extended flange 26.

A bar 27 is mounted for vertical movements at each side of the window frame. These bars 27 are enclosed and covered by the plates 9. The bars 27 are connected with the respective window vent openings at each end by pairs of links 28 having their lower ends pivoted to said bars 27 and their upper ends pivoted to the flanges 26. Between each pair of links 28 there is a support 29. The supports 29' are preferably cylindrical in cross-section and have their outer ends rigid with the plates 9 and their inner ends rigid wth the plates 7. Thus, these supports 29 extend across the spaces 11 between the two links 28 of each pair of said links.

The lower ends of the bars 27 have pinand-slot connection 30 with an arm 31 rigid with a rock shaft 32. The rock shaft 32 has its ends journalled for rocking movements in the. -plates 7 and has at one end a lever 33 whereby said shaft 32 may be rocked.

The upper end of each window frame comprises a plate shaped to provide a horizontal portion 34 and a portion 35 extending downwardly and outwardly to engagement with the flange 5 of the uppermost bar 3. The joint between the bar 3 and said plate may be rendered impervious by solder 36 or other suitable material. The lower edge of the part 35 is bent outwardly and upwardly to provide a portion 37 abutting against a bar 38 anchored in the building wall.

The lower portion of each window frame comprises a plate 39 inclining upwardly and outwardly to engagement with the lowermost bar 3, an impervious joint being obtained by a. quantity of solder 40 or other appropriate sealing material. The plate 39 has a downwardly and out-extended portion 41 secured in some appropriate fashion to the lower wall of the window opening.

The panes 18 may be made of glass or other transparent material and, if desired, may be made of so-called non-breakable glass. It is impossible for the occupants of the building to remove these panes, because the upper edges thereof are overlapped by the outer edges of the parts 16 which cannot be detached from the bars 15.

When it is desired to open the ventilators, the lever 33 is moved downwardly to the position indicated by dotted lines in Fig. 3, thus moving upwardly both bars 27 and thereby moving the links 28 along the support 29. The first portion of the upward movement of the bars 27 raises the closures for the venti-. lating openings sufiiciently to disengage the flanges 22 from the bar structures 15-16. Continued upward movement of the bars 27 effected by rocking the shaft 32. moves the closures inwardly and downwardly onto the bar structures -16, which constitute rigid supports for the closures in the open position of the latter. lVhen it is desired to close the vent openings, it is only necessary to raise the lever 33, thereby turning the shaft 32 in a direction to move the bars 27 downwardly, causing the links 28 to car'rythe closures to the closed positions in which the flanges 22 are seated against the bar members 16, and in which the flanges 23 are seated against the flan es 6.
